ScarletComponentData

class lsst.meas.extensions.scarlet.ScarletComponentData(xy0: tuple, extent: tuple, center: tuple, model: numpy.ndarray)

Bases: object

Data for a component expressed as a 3D data cube

For now this is used for scarlet main source models because their structure is too complex to persist in the same way that scarlet lite components can be persisted.

Note that both xy0 and extent use lsst (x, y) convention, not the scarlet/C++ (y, x) convention.

Attributes:

xy0 : tuple of int

The lower bound of the components bounding box.

extent : tuple of int

The (width, height) of the component array.

center : tuple of int

The center of the component.

model : numpy.ndarray

The model for the component.

Methods Summary

asDict()	Return the object encoded into a dict for JSON serialization
fromDict(data)	Reconstruct ScarletComponentData from JSON compatible dict

Methods Documentation

asDict() → dict

classmethod fromDict(data: dict) → lsst.meas.extensions.scarlet.io.ScarletComponentData

Reconstruct ScarletComponentData from JSON compatible dict

Parameters:

data : dict

Dictionary representation of the object

Returns:

result : ScarletComponentData
